[Solved] Changing building facing

[Ironside]

Hello, is it possible to change the facing of a building with triggers?
I believe Set Unit Facing won't work on buildings.

 

[WaterKnight]

function SetImmovableUnitFacing takes unit u, real a returns nothing
    call SetUnitPosition(u, GetUnitX(u), GetUnitY(u))
    call SetUnitFacing(u, a)
endfunction

Ok I'll try it out, thank you.

By the way, do you know how to get the angle towards which a spell was casted (it's casted by a building so I can't use GetUnitFacing(GetTriggerUnit()).

 

[WaterKnight]

Atan2(GetSpellTargetY() - GetUnitY(GetTriggerUnit()), GetSpellTargetX() - GetUnitX(GetTriggerUnit()))

You want to get alpha. Opposite is y difference, adjacent x difference. Tan alpha is opposite divided by adjacent, so take arctan from that. Atan2 ensures that there is no division by zero.

Awesome, I'll try it out right away.

EDIT: it worked, this is solved.

It can also be done by Action: Unit - Make (Your building) <gen> face (your choice) degrees facing over (your choice) seconds
You will be the one to select it's events and conditions. Hope it would help.
